Description

Technical Field

[0001] The utility model relates to the field of casing machines, in particular to an automatic casing machine. Background Technique

[0002] When electronic ceramic components, such as resistors, fuse tubes, and diodes, are produced, their main bodies and two pins are in a straight line. During packaging, the two pins are fixed separately with tape and then wound into a disc shape. In some circuit environments, the main body needs to be wrapped with an insulating heat shrink tube. Since the heat shrink tube after winding is usually flat, at present, many processing factories still adopt manual operation: first cut the heat shrink tube to a fixed length, then put the heat shrink tube on the main body of the electronic ceramic component, and then send the electronic ceramic component into an oven to make the heat shrink tube wrap the main body of the electronic ceramic component. Before putting the heat shrink tube on the main body of the electronic ceramic component, it is necessary to squeeze the heat shrink tube to make the heat shrink tube become a round tube again before it can be put on the main body of the electronic ceramic component. This kind of operation is time-consuming and laborious, resulting in great waste. Content of the Utility Model

During operation, the heat shrink tube is clamped between the driving gear shaft and the driven gear shaft, and the driving gear shaft and the driven gear shaft cooperate to open the heat shrink tube and sleeve it on the outside of the electronic ceramic component on the electronic ceramic component tape. By using the driving gear shaft and the driven gear shaft to clamp and feed the heat shrink tube, the heat shrink tube is changed from a flat state to a round tube state while realizing the transportation of the heat shrink tube, and thus the automatic sleeving of the heat shrink tube is realized; by setting an electronic ceramic component tape unwinding mechanism, a heat shrink tube pre-sleeving mechanism, a heat shrink tube pushing mechanism, a heat shrink tube heating mechanism and an electronic ceramic component tape winding mechanism, the processes of automatic feeding of electronic ceramic components, automatic heat shrink tube sleeving and automatic winding of electronic ceramic components are realized, the production efficiency is improved, and the production cost is reduced.
